Genetic information | Instead of the whole open reading frame of exon2 of Cx43 (Gja1), a loxP sites-flanked construct is inserted containing the exon 2 of Cx43. One frt site 3' of the poly(A)-signal is remaining in the genome, upon deletion of a frt sites-flanked neomycin-selection cassette. After cre recombinase-mediated deletion of Cx43, Cx31 (Gjb3) is expressed under the control of the endogenous Cx43 promoter. |
Phenotypic information | Not in the loxP flanked state. After cre recombinase-mediated deletion homozygous Cx43KICx31 mice die during the first 10 days, caused by heart malformation. |
Breeding history | After blastocyst injection the chimeras were bred with C57BL/6NCrl to obtain brown coat colored offspring. This brown offspring was backcrossed to C57BL/6NCrl more than 3 times and one time with flp recombinase deleter mice to delete the selection cassette. |
